[Vm-dev] [OpenSmalltalk/opensmalltalk-vm] primitiveSSLCreate fails sporadically on Windows (#554)

Hi win32 folks,

    coincidentally I found a huge bug with external primitives on win32
Spur VMs.  The bug was the VM code generator not using the EXPORT macro to
export primitive accessor depths.  This macro does nothing on unix & macos
(hence I didn't notice the bug), but is required on win32.  The transparent
forwarding mechanism for primitives is broken by this bug.  Hence any
external primitive that needs to retry to follow a forwarder (e.g. after a
pin operation or a become to grow something, etc) won't retry on win32.  I
fon't know if this will fix the SSL issue on win32.  But it is certainly a
smoking gun.

The bug is fixed in my most recent commit.
